Artichoke Extract
Cynara scolymus
TL;DR
Artichoke leaf extract is a choleretic — it increases bile flow, which is the basis for its effects on functional dyspepsia and its modest cholesterol lowering. Trials show meaningful relief of bloating and post-meal fullness at 320-640 mg/day, and LDL reductions of roughly 4-6% at higher doses over 8-12 weeks.
Ideal For
- Adults with functional dyspepsia, bloating and post-meal fullness
- People who feel heavy or nauseated after fatty meals
- Adults with mildly elevated LDL pursuing diet-first management
- People with NAFLD alongside weight and dietary change
Avoid If
- You have gallstones or any biliary obstruction — increasing bile flow is dangerous here
- You have an allergy to the Asteraceae family, including ragweed and daisies
- You have had a cholecystectomy without discussing it with your clinician
- You are relying on it in place of statin therapy for high cardiovascular risk
- You have unexplained right upper quadrant pain that has not been investigated
Frequently Asked Questions
Overview
Cynara scolymus leaf, not the edible heart, is the medicinal part, and cynarin and luteolin are the compounds that matter. The clearest clinical use is functional dyspepsia: randomised trials show reductions in bloating, early satiety, nausea and post-meal discomfort, likely because bile flow is a rate-limiting step in fat digestion and many people with dyspepsia have sluggish gallbladder emptying. A Cochrane review of artichoke for hypercholesterolaemia found modest but consistent total and LDL cholesterol reductions, driven by luteolin's inhibition of HMG-CoA reductase and increased biliary cholesterol excretion — real, but a fraction of what a statin delivers. There is also reasonable evidence in NAFLD, where trials report reduced liver enzymes and improved ultrasound findings at 600 mg/day of extract. The important safety boundary is biliary obstruction: increasing bile flow against an obstructed duct or an existing stone is exactly the wrong intervention, so gallstone disease must be excluded first.
How It Works
- Cynarin stimulates bile production and gallbladder emptying (choleretic and cholagogue action)
- Improved bile flow enhances emulsification and digestion of dietary fat
- Luteolin inhibits HMG-CoA reductase, reducing hepatic cholesterol synthesis
- Increases biliary excretion of cholesterol, lowering the circulating pool
- Caffeoylquinic acids provide hepatocyte antioxidant protection
- Reduces hepatic steatosis markers and transaminases in NAFLD trials
Benefits & Outcomes
Bile Flow Enhancement
Artichoke extract is a genuine choleretic with controlled trial support.
SIBO Prevention
Artichoke with ginger shows prokinetic promise, which is the mechanistically right target.
Cholesterol Management
A modest, evidence-supported LDL reduction worth stacking with diet — not a statin substitute for high-risk patients.

Safety Information
Potential Side Effects
Generally well tolerated. Flatulence, mild diarrhoea and increased appetite are the most commonly reported. Allergic reactions occur in people sensitised to Asteraceae plants.
Contraindications
Bile duct obstruction, gallstones, Asteraceae allergy, unexplained biliary pain.
Drug Interactions
- No major established interactions
- Theoretical additive effect with bile acid sequestrants
- Possible additive lipid lowering with statins — not a safety concern
- Anticoagulants — theoretical, based on in vitro platelet effects

Dosage Guidelines
Dosage Used in Studies

Best Time to Take
15-30 minutes before the two largest meals
Best Form
Standardised leaf extract, 320-640 mg before meals
Bioavailability
Caffeoylquinic acids are extensively metabolised by gut microbiota to caffeic and ferulic acid derivatives, which are the circulating actives. Plasma levels peak within one to two hours.
Forms Compared

Food & Timing
Shortly before meals — the point is to have bile flowing when fat arrives
